BACKGROUND

1. Field

Example embodiments are directed to circuit boards, connectors, cases,circuit board assemblies, case assemblies, devices and methods ofmanufacturing the same.

2. Description of the Related Art

A Solid State Device (SSD) is a memory data storage device that utilizessolid state memory, for example, flash-type, non-volatile memory) tostore persistent data. SSDs are an alternative to conventional harddrives that have slower memory data access times due to moving parts,for example, rotating disks and/or other moving mechanical parts. Theabsence of moving parts in an SSD may improve electromagneticinterference (EMI), physical shock resistance, and/or reliability.However, SSDs may be more prone to electrostatic discharge (ESD)relative to a conventional servo motor found in a hard drive, where therecording surfaces may be made of a magnetic material that is moreESD-resistive. The ESD problem may be exacerbated by higher memorydensities.

SSDs may have many different structures, sizes, dimensions, volumes,interfaces, and/or compatibilities. Each set of characteristics may bereferred to as a form factor. Two examples are a 1.8 inch and 2.5 inchSerial Advanced Technology Attachment (SATA)-2 standard structures. Ineither structure, the SSD may include one or more of the following, aprinted circuit board, one or more controller integrated circuit (ICs),for example, fine-pitch ball grid array (FPBGA) controllers, one or moreNAND memory ICs, one or more mobile Synchronous Dynamic Random AccessMemory (SDRAM) ICs, one or more voltage detector, one or more voltageregulator, one or more heat sink, one or more diodes, one or moreconnectors, including input/output (I/O) pins and clock (for, examplecrystal) pins, and/or a case.

As a result of a plurality of hard drive specifications, many differentSSDs, having different interfaces, have been developed.
